I have a job that really puts stress on my knees and my knees don't have much cartilage left. My chiropractor recommend Instaflex since I have bad consequences when I take any of the glucosamine pills.
I noticed within a week less discomfort in my knees. I've been taking them for 3 weeks at this point and plan on continuing.
Review about: Instaflex Advanced Joint Support Supplement.
